`RAILROAD-TRACK STRUCTU RE.

SPECIFICATION forming part of Letters Patent N o. 593,166, datedNovember 2, 1897.

Application iiled November 211896. Serial No. 613,034. (No model.)

To @ZZ whom t may concern;

Be it known that EDWARD SAMUEL, formerly a citizen of the United States,residing at Philadelphia, Pennsylvania, but now deceased, did during hislifetime invent certain Improvements in Railroad-Track Structures, ofwhich the following is a specification.

This invention relates to certain improvements in wearing-pieces orrisers used to carry wheels on their flan ges across the intersectingpoints of rail structures.

The object of the invention is to facilitate the manufacture and to lockthe riser to the rails by perforating the rails at intervals, so thatthe metal which forms the riser when in a molten state will pass throughthe perforations and unite under the flange of the rail or to so shapethe perforations tha't the metal within them will lock the riser to thestructure, as clearly described hereinafter.

In the accompanying drawings, Figure 1 is a plan view of a crossing,illustrating the invention. Fig. 2 is an enlarged transverse sectionalView en the line 2 2, Fig. 1. 3 is an enlarged sectional View on theline 3 .3, Fig. l. Fig. 4 is an enlarged sectional view illustrating amodification inwhich is shown the cast metal which unites therail-sections together forming the riser. Fig. 5 is a view of anothermoditcation, and Fig. 6 is a view showing the invention applied toastraight tram-rail.

Referring in the first instance to Figs. 1,2, and 3, A is the main-linerail, and B is the crossing-rail. These rails are secured together inthe present instance by a casting D, the cast metal passing throughperforations in the webs of the rails, thus holding the rails rigidlytogether without the use of bolts or rivets. It will be understood,however, that the invention can be used in rail structures in which therails are bolted or riveted together and may be made entirely of acasting, and while there is illustrated a crossingfrog it will beunderstood that the invention can be used at any crossing or switch-mateor at any point in a rail where it is wished to use a riser.

In the present instance the base of the groove d of the rail A isperforated, as Well as the base of the groove b of the rail B, and

a mold of such form is prepared and applied to the rail that when moltenmetal is poured onto the rail-section it will new through the series ofperforations in the two rails and unite underneath the iiange, forming alock, as clearly shown in Fig. 3. A suitable cap is placed over thegroove of the rail so that the riser will be of a given height.

In some instances a core maybe used when it is wished to cast the tworails together to 6o formthe rail structure, so that a recess will beleft directly under the flange of the rail where the riser is to belocked, so that when the cast-metal section D is cold the core can beremoved and the metal to form the riser can be poured into a suitablecap and through the openings in the 4Bange of the rails, the metalflowing into the space formed by the core and the metal passing throughthe several openings uniting under the flange of the 7o rail.

In Fig. 4 there is shown a modification in which the cast metal whichunites the rails together is allowed to rise through the perforationsand into the groove of the rail to such aheight as may be considerednecessary to form the riser, and the upper surface of this metal may runagainst a chill, so as to give it a harder surface should it be deemednecessary. 8o In Fig. 5 the perforations in the rail are formed at anangle and the lower section of the riser is dispensed with, the metal inthe perforations holding the riser in position.

In Fig. 6 there is shown an improved form 85 of riser applied to a railhaving a straight tram, and it will be understood that the invention maybe applied wherever a wearingplate is required in a structure of thecharacter described.

lVhat is claimed as the invention is- 1. The combination in a trackstructure, of a rail having a series of perforations with the riser orwearing-plate resting upon the rail and having a series of lugsextending into the perforations of the rail and acting to hold the riserin position, substantially as described.

2. The combination of a rail,perforated side flange thereof, with acast-metal riser or wearing-plate having two sections, one above and roo4:. The combination in a, track structure, of

the rails perforated at the point Where a. riser is to be formed, Withcast metal binding the rails together, said metal extending through theperforations and forming the riser, sub- 15 stantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
